本発明は、増加した果実収量を有するナス属lycopersicum植物および本発明に係るナス属lycopersicum植物の種子または果実に関する。また、本発明は、ナス属lycopersicum植物の果実収量を増加するための方法に関する。さらに、本発明は、本発明に係るナス属lycopersicum植物の種子および果実に関する。
DESCRIPTION The present invention relates to the eggplant lycopersicum plant having increased fruit yield and the seeds or fruits of the eggplant lycopersicum plant according to the present invention. The present invention also relates to a method for increasing the fruit yield of Solanum lycopersicum plants. Furthermore, the present invention relates to seeds and fruits of the solanaceous lycopersicum plant according to the present invention.
ナス属lycopersicum植物は、トマト属lycopersicum（Ｌ．）またはトマト属esculentumとも命名され、一般的にトマト植物として知られている。この種の植物は、南米アンデス山脈に起源し、食品としての使用は、メキシコに由来し、スペインによるアメリカ大陸の植民地化によって世界に広がった。その多くの品種は、現在も野外にまたは寒い気候の場合温室において、広く栽培されている。 The solanaceous lycopersicum plant is also named tomato lycopersicum (L.) or tomato esculentum and is generally known as a tomato plant. This type of plant originated from the South American Andes, and its use as a food originated in Mexico and spread throughout the world through the colonization of the American continent by Spain. Many of its varieties are still widely cultivated in the open air or in the greenhouse in the cold climate.
トマトは、多くの料理、ソース、サラダおよび飲料中に原料としてまたは成分として、多様な方法で消費されている。トマトは、植物学上果実としてみなされているが、料理目的では野菜であると考えられている。トマトは、有益な健康効果を有し得るリコピンを豊富に含む。ナス属lycopersicumは、Solanaceaeナス科に属する。この植物は、典型的には、１〜３メートルの高さに成長し、弱い茎を有するため、多くの場合、地面に寝そべりまたは他の植物に吊るす。この植物は、多くの場合、温暖気候で屋外に一年生として成長するが、本来の生息地では多年生である。より小さい品種およびより大きな品種が知られているが、普通のトマトの平均重量は、約１００グラムである。 Tomatoes are consumed in a variety of ways, either as an ingredient or as an ingredient in many dishes, sauces, salads and beverages. Tomato is considered a fruit in botany, but is considered a vegetable for cooking purposes. Tomatoes are rich in lycopene that can have beneficial health benefits. The solanaceous lycopersicum belongs to the Solanaceae solanaceae family. Because this plant typically grows 1 to 3 meters high and has a weak stem, it often lies on the ground or hung on other plants. This plant often grows as a perennial outdoor in a warm climate, but perennial in its native habitat. Smaller and larger varieties are known, but the average weight of a normal tomato is about 100 grams.
ナス属lycopersicum植物の経済的重要性を考慮すると、植物育種分野において、この植物の果実収量を増加させることは、引き続き望まれる。 In view of the economic importance of the solanaceous lycopersicum plant, it is still desirable to increase the fruit yield of this plant in the field of plant breeding.
過去数十年間に、育種は、主に、収量、耐病性、および均一な熟成および味などの果実品質面に集中した。収量の改良は、新たな生産方法、改良された害虫管理、および新たな生産方法により適合する品種によって、達成されている。植物当たりに５個または１５個の果実を多く有する新品種は、収量を２〜４％に増加した。 In the past decades, breeding has mainly focused on fruit quality aspects such as yield, disease resistance, and uniform ripening and taste. Yield improvements have been achieved by new production methods, improved pest management, and varieties that are more adapted to new production methods. New varieties with as many as 5 or 15 fruits per plant increased yield to 2-4%.
高収量品種の開発は、トマトの収量を決定する性質に関する知識の不足により妨げられた。仮説によると、従来の３枚の葉の代わりに、トラスの間に２枚の葉を有するトマト品種は、葉面積指数（ＬＡＩ）が維持される場合、果実に向かって同化をシフトすることができ、より高い収量が得られる。 Development of high-yield varieties has been hampered by a lack of knowledge about the properties that determine tomato yield. According to the hypothesis, instead of the traditional three leaves, tomato varieties with two leaves between trusses can shift assimilation towards the fruit if the leaf area index (LAI) is maintained. And higher yields are obtained.
トラスの間に２枚の葉を有するナス属lycopersicumの栽培品種は、ＷＯ２００９／０２１５４５に記載されている。ＷＯ２００９／０２１５４５は、ナス属lycopersicumの近縁野生種、すなわちナス属pennelliに発見されたＳＰ３Ｄプロモータが、トラスの間に２枚の葉を有するナス属lycopersicumを提供することができ、よって、果実の収量を増加することができることを開示している。しかしながら、その後の実験によって、例えば、ナス属pennelliのＳＰ３Ｄ遺伝子またはプロモータをナス属lycopersicumに移入することによって提供されたトラスの間に２枚の葉を有する表現型は、常に安定しておらず、得られた後代の果実収量を妨げることが示された。 A cultivar of Solanum lycopersicum having two leaves between trusses is described in WO2009 / 021545. WO 2009/021545 provides a closely related wild species of Solanum lycopersicum, that is, the SP3D promoter found in Solanum pennelli can provide Solanum lycopersicum with two leaves between trusses. It is disclosed that the yield can be increased. However, in subsequent experiments, for example, the phenotype with two leaves between truss provided by transferring the SP3D gene or promoter of Solanum pennelli into Solanum lycopersicum is not always stable, It was shown to interfere with the yield of the resulting progeny fruits.
本発明の目的は、特に、増加した果実の収量を有するナス属lycopersicum植物を提供することである。本発明のさらなる目的は、トラスの間に２枚の葉を有する表現型を安定化することによって、ナス属lycopersicum植物の果実収量をさらに増加させることである。 The object of the present invention is in particular to provide Solanum lycopersicum plants with increased fruit yield. A further object of the present invention is to further increase the fruit yield of Solanum lycopersicum plants by stabilizing the phenotype with two leaves between trusses.
上記の目的は、特に、添付の特許請求の範囲に概説された本発明のナス属lycopersicum植物を提供することによって達成される。 The above objectives are achieved in particular by providing the solanaceous lycopersicum plants of the present invention as outlined in the appended claims.
具体的には、上記の目的は、特に、ナス属pennelliのＳＰ３Ｄ遺伝子およびＳＰ遺伝子または少なくともそのプロモータ配列を含み、増加した果実収量を有するナス属lycopersicum植物によって達成される。 Specifically, the above objectives are achieved in particular by the solanaceous lycopersicum plant comprising the SP3D gene and the SP gene of Solanum pennelli or at least its promoter sequence and having an increased fruit yield.
驚くことに、本発明者らは、ナス属pennelliのＳＰ３Ｄ遺伝子およびＳＰ遺伝子の両方をナス属lycopersicumに組み合わせることによって、「トラスの間に２枚の葉を有する表現型」を安定に提供することができ、ナス属lycopersicum植物の全体的な果実収量を増加することができることを発見した。果実収量の増加に関して、トラス数の３０％の増加が観察された。 Surprisingly, the present inventors stably provide a “phenotype having two leaves between trusses” by combining both the SP3D gene and the SP gene of Solanum pennelli with Solanum lycopersicum. And found that the overall fruit yield of Solanum lycopersicum plants can be increased. Regarding the increase in fruit yield, a 30% increase in the number of trusses was observed.
本発明の記載において、「遺伝子」という用語は、調節領域、転写領域および他の機能的な配列領域に関連付けられている遺伝単位に対応するゲノム配列の配置可能領域として理解すべきである。この用語「遺伝子」は、少なくとも、プロモータ領域および転写またはコード領域を含むゲノム配列を意味する。 In the description of the present invention, the term “gene” should be understood as a placeable region of a genomic sequence corresponding to a genetic unit associated with regulatory regions, transcription regions and other functional sequence regions. The term “gene” means a genomic sequence comprising at least a promoter region and a transcriptional or coding region.
ナス属pennelliという植物種は、トマト植物の近縁野生種である。ナス属pennelliの遺伝子は、従来の遺伝子移入または現代の分子生物学技術、例えば形質転換によって、ナス属lycopersicum植物に容易に導入することができる。トマト植物の他の近縁野生種のＳＰ遺伝子およびＳＰ３Ｄ遺伝子とトマト植物のＳＰ遺伝子およびＳＰ３Ｄ遺伝子または少なくともそのプロモータとの遺伝的な近似性を考慮すると、ナス属neorickii、ナス属chmielewskii、ナス属chilense、ナス属parviflorum、ナス属pimpinellifoliumおよびナス属peruvianumは、本発明の文脈内に含まれると考えられる。 The plant species of the genus Pennelli is a wild relative of the tomato plant. The gene of Solanum pennelli can be easily introduced into Solanum lycopersicum plants by conventional gene transfer or modern molecular biology techniques such as transformation. Considering the genetic closeness of the SP gene and SP3D gene of other related wild species of tomato plants with the SP gene and SP3D gene of tomato plants or at least the promoter thereof, Solanum neorickii, Solanum chmielewskii, Solanum chilense Eggplant parviflorum, Eggplant pimpinellifolium and Eggplant peruvianum are considered to be included within the context of the present invention.
当該ＳＰ３Ｄ遺伝子の転写領域は、配列番号１を有する配列と少なくとも９０％、例えば９１％、９２％、９３％または９４％、好ましくは少なくとも９５％、例えば９６％、９７％、９８％または９９％、より好ましくは実質的に１００％の配列同一性を有するアミノ酸配列を含むタンパク質をエンコードする。本発明の文脈において、配列同一性は、所定の配列に同様の配列のアミノ酸の数が所定の配列番号を有するアミノ酸の総数で割り、１００％を乗じることを意味する。 The transcription region of the SP3D gene is at least 90%, such as 91%, 92%, 93% or 94%, preferably at least 95%, such as 96%, 97%, 98% or 99%, with the sequence having SEQ ID NO: 1. More preferably encodes a protein comprising an amino acid sequence having substantially 100% sequence identity. In the context of the present invention, sequence identity means that the number of amino acids of a similar sequence divided by the total number of amino acids having a given sequence number multiplied by 100% for a given sequence.
当該ＳＰ遺伝子の転写領域は、配列番号２を有する配列と少なくとも９０％、例えば９１％、９２％、９３％または９４％、好ましくは少なくとも９５％、例えば９６％、９７％、９８％または９９％、より好ましくは実質的に１００％の配列同一性を有するアミノ酸配列を含むタンパク質をエンコードする。 The transcription region of the SP gene is at least 90%, such as 91%, 92%, 93% or 94%, preferably at least 95%, such as 96%, 97%, 98% or 99%, with the sequence having SEQ ID NO: 2. More preferably encodes a protein comprising an amino acid sequence having substantially 100% sequence identity.
留意すべきことは、ナス属pennelliのＳＰ３Ｄ遺伝子およびＳＰ遺伝子を組み合わせることによって提供された本発明の「果実収量を増加した」安定な表現型は、エンコードされたタンパク質に起因するものではなく、両方の遺伝子の転写調節に起因するものであることである。具体的には、転写を調節する転写配列の少なくともプロモータ領域、すなわちゲノム領域の上流は、観察された効果に寄与する。換言すれば、「増加した果実収量」という本発明の特徴は、ナス属lycopersicumに比べて、ナス属pennelliにおけるＳＰおよびＳＰ３Ｄの転写調節の違いに起因する。特に、トランスジェニック植物の場合に、転写配列またはｃＤＮＡ配列の前に両方の遺伝子の少なくともプロモータ配列を操作可能に導入することは、本発明の表現型を提供する。 It should be noted that the “fruit-enhanced” stable phenotype of the invention provided by combining the SP3D and SP genes of Solanum pennelli is not due to the encoded protein, both This is due to the transcriptional regulation of the gene. Specifically, at least the promoter region of the transcription sequence that regulates transcription, ie upstream of the genomic region, contributes to the observed effect. In other words, the feature of the present invention of “increased fruit yield” is due to the difference in transcriptional regulation of SP and SP3D in Solanum pennelli compared to Solanum lycopersicum. In particular, in the case of transgenic plants, operably introducing at least the promoter sequence of both genes before the transcriptional or cDNA sequence provides the phenotype of the present invention.
したがって、特に好ましい実施形態によれば、本発明は、配列番号３を有するプロモータ配列により制御されるＳＰ３Ｄ遺伝子またはｃＤＮＡ配列および／または配列番号４を有するプロモータ配列により制御されるＳＰ遺伝子またはｃＤＮＡ配列を有するナス属lycopersicum植物に関する。 Thus, according to a particularly preferred embodiment, the present invention provides an SP3D gene or cDNA sequence controlled by a promoter sequence having SEQ ID NO: 3 and / or an SP gene or cDNA sequence controlled by a promoter sequence having SEQ ID NO: 4. It relates to an eggplant lycopersicum plant having.
本明細書中において、ＳＰ３ＤのｃＤＮＡ配列は、配列番号５として提供され、ＳＰのｃＤＮＡ配列は、配列番号６として提供される。 In the present specification, the cDNA sequence of SP3D is provided as SEQ ID NO: 5, and the cDNA sequence of SP is provided as SEQ ID NO: 6.
本発明によれば、当該ナス属lycopersicum植物は、ヘテロ接合型ナス属pennelliまたはホモ接合型ナス属pennelliのＳＰ遺伝子およびＳＰ３Ｄ遺伝子を含むことができる。すなわち、当該ナス属lycopersicum植物内の少なくとも１つの対立遺伝子は、ナス属pennelliのＳＰ遺伝子を含み、当該ナス属lycopersicum植物の少なくとも１つの対立遺伝子は、ナス属pennelliのＳＰ３Ｄ遺伝子を含む。しかしながら、驚くことに、本発明者らは、本発明のプロモータまたは遺伝子の一方が両方の対立遺伝子にホモ接合型として存在する場合、果実収量のさらなる改善、例えばトラス数のさらなる改善を得ることができることを観察した。ナス属pennelliの両方の遺伝子がホモ接合型として存在する場合、果実収量の最適な増加が得られる。 According to the present invention, the solanaceous lycopersicum plant can contain the SP gene and SP3D gene of heterozygous eggplant genus pennelli or homozygous eggplant genus pennelli. That is, at least one allele in the solanaceous lycopersicum plant contains the SP gene of Solanum pennelli, and at least one allele of the solanaceous lycopersicum plant contains the SP3D gene of Solanum pennelli. Surprisingly, however, we can obtain further improvements in fruit yield, such as further improvement in truss number, when one of the promoters or genes of the invention is present as a homozygous form in both alleles.

以下の実施例を用いて、本発明をさらに詳細に説明する。実施例は、添付の図面を参照する。 The invention is explained in more detail using the following examples. Examples refer to the attached drawings.
ＳＰ遺伝子が増加した果実収量の表現型を安定化することができるか否かを確認するために、１００個の遺伝子移入植物を栽培した。具体的には、これらの植物は、ナス属pennelliからのＳＰ３ＤおよびＳＰをナス属lycopersicum（またはトマト属esculentum）に遺伝子移入することによって得られた。両方の遺伝子の存在は、標準分子解析によって確認した。 In order to confirm whether the fruit yield phenotype with increased SP gene could be stabilized, 100 transgenic plants were cultivated. Specifically, these plants were obtained by introgressing SP3D and SP from Solanum pennelli into Solanum lycopersicum (or Tomato esculentum). The presence of both genes was confirmed by standard molecular analysis.
植物は、標準条件下で成長させられ、トラス間の葉数は、カウントされる。図１に示すように、トラス間の葉の平均数は、２枚から３枚の間に変動する。さらに、図１は、ナス属pennelliからのホモ接合型ＳＰ３Ｄは、ヘテロ接合型ＳＰ３Ｄに比べて、よりも少ないトラス間の葉数をもたらしたことを示している。 Plants are grown under standard conditions and the number of leaves between trusses is counted. As shown in FIG. 1, the average number of leaves between trusses varies between 2 and 3. Furthermore, FIG. 1 shows that homozygous SP3D from Solanum pennelli resulted in fewer inter-truss leaf counts compared to heterozygous SP3D.
ホモ接合型pennelliのＳＰ（ＳＰｐｅｎ／ｐｅｎ）が、ホモ接合型pennelliのＳＰ３Ｄ（ＳＰ３Ｄｐｅｎ／ｐｅｎ）またはヘテロ接合型pennelliのＳＰ３Ｄ（ＳＰ３Ｄｐｅｎ／ｐｅｎ）と組み合わせたヘテロ接合型pennelliのＳＰ（ＳＰｐｅｎ／ｅｓｃ）よりも、トラス間に２枚の葉を有する表現型により大きく寄与しているか否かを検査するために、図２において、戻し交雑科に存在した異なるハプロタイプとトラス間の葉数との図面を作成した。図２に見られるように、ＳＰｐｅｎ／ｐｅｎおよびＳＰ３Ｄｐｅｎ／ｐｅｎの両方が植物においてホモ接合型pennelliとして存在する場合、トラス間の葉の平均数は、２枚である。一方、他のすべての組み合わせの場合、トラス間の葉の平均数は、２．２５枚以上である。図１と比較すると、図２は、pennelliの存在は、トラス間に２枚の葉を有する表現型の安定性に寄与していることを示している。 Homozygous pennelli SP (SP pen / pen ) is combined with homozygous pennelli SP3D (SP3D pen / pen ) or heterozygous pennelli SP3D (SP3D pen / pen ) SP (SP In order to examine whether the phenotype with two leaves between trusses contributes more than ( pen / esc ), the number of leaves between different haplotypes and trusses in the backcross family in FIG. And made a drawing. As seen in FIG. 2, when both SP pen / pen and SP3D pen / pen are present as homozygous pennelli in plants, the average number of leaves between trusses is two. On the other hand, in the case of all other combinations, the average number of leaves between trusses is 2.25 or more. Compared with FIG. 1, FIG. 2 shows that the presence of pennelli contributes to the stability of the phenotype with two leaves between trusses.
本発明の植物の果実収量を評価するために、以下の交雑スキームに従って、Moneyberg（ナス属lycopersicum）バックグラウンドで、pennelliのＳＰ３ＤおよびpennelliのＳＰの両方を遺伝子移入することによって得られた植物のトラスの数をカウントした。 To assess the fruit yield of the plants of the present invention, the plant truss obtained by introgressing both pennelli SP3D and pennelli SP in a Moneyberg (Nas lycopersicum) background according to the following crossing scheme: Counted the number of.
これらの植物は、６月から１０月までの間に成長させられ、各々の植物のトラス数をカウントした。図３は、４つの異なる遺伝子型のトラスの数を示している。図３に明らかに示すように、pennelliのＳＰ３ＤおよびpennelliのＳＰの両方がホモ接合型として存在した場合、植物のトラスの量は、改善される。 These plants were grown between June and October and the truss number of each plant was counted. FIG. 3 shows the number of trusses of four different genotypes. As clearly shown in FIG. 3, the amount of plant truss is improved when both pennelli SP3D and pennelli SP are present as homozygous.
